Chicken Or Egg First + Circadian Rhythm

Origin Of Circadian Rhythm

For Archaic Genes Sunlight Was The Only Source Of Energy

Circadian Rhythm and Plant Genes Fuel-Up

(1) One of the routes, of the mechanisms of energy absorption, by which some archaegenes became and function as active energy packages, i.e. became living organisms:

(2) My elsewhere note on the Origin of Circadian Rhythm applies neatly in Plant Genes Fuel-Up, too. Both these processes fit in with comprehension that genes-genomes are living organisms.

(3) Genome observed "Oscillating" in coordination with circadian rhythm:

But circadian rhythm may be innate gene-genome characteristic, inborn/brought-about at the energetic conditions during the genesis of genes in the process of phasing from chemical olygomer to replicating life, to genes, to base life energy packages …..

Chapter I, G. Life's Drive and Purpose

"1. If one accepts, intuitively and logically, Pasteur's observation that all life must come from previously existing life, then the answer to "what makes a mono- and poly-cell life-form a Life" is the answer to "what makes some molecular associations in cells LIVES", and vice versa. It is the "lifehood" of genes that makes us and all other forms of life on Earth living organisms, and evolution has been the route of Life's ever more complexing progress since the first replication of the first gene."

It occurs to me that the point of the above post has not been duly obvious, i.e. that it has not clearly explained the source of Earth's organism's Circadian Rhythm.

I therefore wish to add this to the original post, the emphasis that for the archaic genes, parents of all Earth's Life, direct sunlight was the only source of energy. Hence circadian rhythm is most certainly an innate gene-genome characteristic.

Chicken Or Egg First?

A) NOTTINGHAM, England, May 26 2006 (UPI):

>>>British scientists and a farmer say they have solved the question

of what came first, the chicken or the egg, saying the egg

definitely was the original.

Evolutionary genetics Professor John Brookfield of the University of

Nottingham told The Independent the same DNA code of the chicken and

the egg it came from proves the egg was first.

He said a living organism, in this case a chicken, keeps the same

DNA structure as it did when an embryo in the egg, The Independent

reports, "Therefore, the first living thing that we could say

unequivocally was a member of the species would be this first egg,"

said Brookfield.

King's College London Professor David Papineau and Charles Bourns,

chairman of the Great British Chicken trade board, agreed. They said

the egg could be a mutant change from any other animal that then

produced the chicken but not the other way around.<<<

B)

This subject's matter is simply and only semantics/definitions. For

the purpose of chicken-egg discussion the first egg that yielded a

narrowly defined new-species-chicken was the first member of this

defined species. However, in life-evolution the new egg is

definitely not the first "living thing" that represents the new

chicken species. It is the egg's genome, a living organism

consisting of a commune of interdependent genes who long ago lost

their individual once-upon-the-time pre-celling-era capability of

independent living (replication), that is the first living thing of the species.

And this genome came to be in the egg by way of …

>>> During DNA duplication its precursors with progressively narrowed

potential give rise to progeny that adopt one of two or more

divergent fates. The choice is influenced by intricate regulatory

networks acting at multiple levels. Early in the DNA duplication

course precursors show low-level activation of all progeny genetic

programs. Bias toward a given lineage comes from environmental

inputs that activate powerful positive- and negative- feedback

loops, which work in concert to impose selective gene expression

patterns.<<<
